Technical Specs & Certifications
Beauty STC Manufacturing Co., Ltd. designs and produces high-performance tunable white and full-color RGB/RGBW LED lighting systems marketed as “light changing” solutions. These systems enable dynamic adjustment of color temperature (typically 2700K to 6500K for tunable white) or full-spectrum color output. Key technical specifications adhering to our stringent quality standards are detailed below, focusing on your requested parameters.
Lumens per Watt (lm/W) efficacy varies significantly based on the specific “light changing” technology employed. For high-CRI tunable white systems (2700K-6500K), Beauty STC achieves industry-leading efficacies ranging from 85 to 105 lm/W at 3000K under standard testing conditions (25°C ambient). This is accomplished through optimized multi-channel LED arrays and proprietary driver efficiency. Full-color RGB or RGBW systems inherently exhibit lower efficacy due to the inclusion of less efficient colored LEDs; our premium units maintain 65 to 85 lm/W in white light mode (using the white diode) and 50 to 70 lm/W during saturated color output. All efficacy figures are measured per IES LM-79 standards at full rated power and represent the typical performance of our commercial-grade fixtures, not peak laboratory results. Efficacy is maintained through advanced thermal management ensuring junction temperatures remain below critical thresholds during extended operation.
Color Rendering Index (CRI) performance is a core differentiator for Beauty STC. All tunable white and high-CRI RGBW products targeting professional applications guarantee a minimum CRI of 92, with R9 (saturated red) values consistently exceeding 50 and often reaching 70+. This is achieved using meticulously binned premium phosphor-converted LEDs, often incorporating violet-pump technology combined with multiple phosphor blends for superior spectral continuity. We rigorously test CRI across the entire tunable range (2700K-6500K), ensuring values never drop below 90 at any CCT setting, a critical requirement for retail, hospitality, and healthcare environments where accurate color perception is non-negotiable. This commitment to spectral quality is validated through third-party TM-30-15 reports available upon request.
IP (Ingress Protection) ratings are application-dependent but strictly engineered into the fixture design. For indoor tunable systems (e.g., architectural cove lighting, retail track heads), Beauty STC typically achieves IP20 or IP40 ratings, sufficient for dry, controlled environments. For outdoor or demanding indoor locations like bathrooms, pools, or retail refrigeration units, our sealed tunable fixtures are rated IP65 for dust-tight operation and protection against low-pressure water jets from any direction. Critical outdoor RGB landscape or facade systems undergo enhanced sealing and achieve IP67 certification, surviving temporary immersion up to 1 meter. Crucially, the IP rating applies consistently across the entire fixture, including integrated drivers and control modules, verified through extended duration testing per IEC 60529 standards. No compromise on the IP rating occurs due to the tunable functionality.
Beauty STC’s quality assurance underpins these specifications. We implement a rigorous three-stage binning process for LEDs, far exceeding standard practices, to ensure exceptional chromaticity consistency (within MacAdam 2-3 steps) across all CCTs and colors, batch after batch. Our thermal management systems utilize aerospace-grade aluminum alloys and optimized heat sink geometries, preventing lumen depreciation and CRI degradation even under continuous full-power operation in high ambient temperatures. Every tunable driver undergoes 100% functional testing for smooth dimming, precise color mixing, and stable output over 50,000+ hours. This commitment to engineering excellence, backed by ISO 9001-certified manufacturing processes and comprehensive in-house photometric laboratories, ensures our “light changing” LED systems deliver the specified lumens/Watt, unwavering CRI >90 performance, and reliable IP protection throughout their operational lifespan, setting the benchmark for professional lighting applications globally.

Application Scenarios
Light changing LED lighting systems, encompassing both RGB color-changing and tunable white (CCT adjustable) technologies, offer significant value in hospitality, retail, and commercial environments when applied thoughtfully. Their implementation requires careful consideration of the specific space’s function, user experience goals, and technical requirements to avoid visual clutter or discomfort.
In hotels, light changing systems excel in creating dynamic atmospheres and enhancing guest well-being. The main lobby and reception area benefit significantly from RGB systems capable of smooth, slow color transitions to set the mood for events, holidays, or simply to reflect the hotel’s brand identity, though the palette should remain sophisticated rather than garish. Guest rooms are prime candidates for high-quality tunable white systems, allowing occupants to shift from energizing cooler white light (5000K-6500K) in the morning to relaxing warmer tones (2700K-3000K) in the evening, supporting natural circadian rhythms. Spas, pools, and wellness areas utilize subtle RGB color therapy effects, often using slow fades between calming blues and soft ambers, but should avoid rapid changes that disrupt relaxation. Crucially, guest room RGB systems are generally less appropriate than tunable white, as overly dynamic color changes can feel gimmicky and disturb sleep; if used, they should be easily disabled by the guest. Restaurants and bars within hotels use tunable white to adjust ambiance from bright and lively during brunch to warm and intimate for dinner, while feature walls or under-bar lighting might employ restrained RGB for accent.
Malls leverage light changing technology primarily for visual impact, brand differentiation, and guiding customer flow. Grand entrances and central atriums are ideal for large-scale, high-impact RGB installations capable of creating dramatic color washes or dynamic scenes for seasonal promotions or events, ensuring the movement is slow and the colors harmonious to avoid overwhelming visitors. Individual retail storefronts and display windows strategically use tunable white to optimize product presentation – cooler temperatures for electronics or cosmetics to convey freshness, warmer tones for textiles or wood furniture to evoke coziness. Accent lighting within stores, such as on mannequins or key merchandise, can employ focused RGB to make specific items pop, though saturation should be moderate to prevent color distortion of the products themselves. Food courts benefit from tunable white systems that enhance the appeal of food, using slightly warmer tones to make dishes look more appetizing compared to the cooler light often found in supermarkets. It is essential to avoid chaotic or rapidly changing RGB effects in high-traffic walkways, as this can cause visual discomfort and detract from the shopping experience; subtlety and intentionality are key.
Offices present a more nuanced application, where tunable white systems deliver the most proven benefits for occupant well-being and productivity, while RGB color-changing has very limited, specific uses. Tunable white is highly effective in open-plan offices, meeting rooms, and focus areas, allowing light temperature to be adjusted throughout the day – cooler, brighter light (4000K-5000K) during core work hours to boost alertness and concentration, shifting to warmer, softer light (3000K-3500K) later in the day to reduce eye strain and support a smoother transition out of work. Collaboration zones might use slightly warmer tunable white to foster a relaxed, creative atmosphere. RGB systems are generally unsuitable for primary task lighting in workspaces, as dynamic color changes are distracting and unprofessional. Potential exceptions include very subtle, slow-changing RGB in dedicated break rooms or wellness rooms for brief relaxation periods, or as a non-distracting architectural accent in a large reception area, but even here, the effect must be minimal and easily overridden. The primary focus in offices should be on high-quality, glare-controlled tunable white systems integrated with occupancy and daylight sensing.
Installation demands meticulous planning and execution for reliable, effective results. Always prioritize robust control systems compatible with the scale of the project; large hotels or malls typically require professional protocols like DMX512, DALI with DT6, or robust wireless mesh systems (e.g., Bluetooth Mesh, Zigbee) over simple Wi-Fi apps, ensuring reliability and scalability. Integrate the lighting controls with Building Management Systems (BMS) or hotel property management systems where beneficial, such as automatically shifting to warmer tones in guest rooms during evening hours. Thermal management is critical, especially for high-density RGB modules; ensure fixtures have adequate heatsinking and maintain specified minimum clearances from insulation or other materials to prevent lumen depreciation and color shift. Pay strict attention to power requirements and circuit loading, particularly for RGB systems which may have higher inrush currents; dedicated circuits with appropriate dimmers or drivers are often necessary. Commissioning is non-negotiable – meticulously program scenes, transition speeds, and schedules on-site. In hospitality and retail, transitions should be slow (often 30-60 seconds minimum for full shifts) to avoid visual disturbance; rapid changes are almost never appropriate in these environments. Finally, provide comprehensive, intuitive user interfaces – hotel staff and facility managers need simple, reliable controls, not complex programming interfaces, so invest in well-designed wall stations or tablet-based master controllers with clear presets. Always adhere strictly to local electrical codes and safety standards during installation.
